1 Claim. (Cl. 51 -179) This invention relates to a machine for-grindingthe wheels of locomotives and railroad cars.

It is aimed to provide a readily portable :structure which may beapplied to a pair of track rails and fastened thereto removably andwhich carries one or more grinding wheels for grinding engagement withthe locomotive or car wheels,

l5 become apparent from a consideration of the description followingtaken in connection with accompanying drawings illustrating an operativeembodiment.

In said drawings:

Figure 1 is a view showing my improvements in elevation, partly brokenaway, attached to track rails and in operative relation to locomotive orcar wheels;

Figure 2 is a plan View of the parts of Figure 1;

Figure 3 is an edge elevation of the parts of Figure 1;

Figure 4 is an enlarged elevation, partly broken away, particularly ofone of the grinding units,

and

Figure 5 is a vertical section taken on the plane of line 55 of Figure4.

Referring specifically to the drawings wherein like reference charactersdesignate like or similar parts, designates a supporting bar or beam,

5 preferably of channel or angle form in cross section, the same alsopreferably having webs H welded thereto to reinforce the same. Thesupport 10 and parts mounted thereby are portable and are showndetachably fastened rigidly to a 40 pair of track rails l2. To this end,bracket 13 and M are carried by the support 10, the former being weldedthereto and the latter preferably being adjustable and secured to thebar by means of a bolt [5. Such brackets 45 engage the inner faces ofthe rails as at the ball and portions of the web, as shown. In addition,lugs 16 are welded or otherwise rigidly fastened to the support In anddepend from the same. Clamping bolts l1 are screw threaded to the lugs50 16 and bear against the webs of the rails 12 and thereby removablyand rigidly bear against the webs of the rails l2. Reinforcing webs I8preferably extend outwardly from the lugs l6 between the pairs of boltsl1 of each lug I6.

55 Brackets or shelves generally of angle form are 'tical flange or wallof.

l3 and I LpreferabIy employed at 19, preferably-welded to the verthesupport l0 and'they preferably have reinforcing webs as at 2 0, -weldedin place. Each bracket 19 has a horizontal wall 2| on which a bedplate22 is rigidly mounted as by means of welding.

Each bedplate 22 has a dovetail portion 23 extending transversely of thetrack rails l2 and slidably engaged by a dovetail recess or groove 24 ofa laterally adjustable plate 25. Such plates 25 have dovetail recesses26 extending longitudinally relatively to the rails l2 and slidablyengaged by a plate 21, having a dovetail portion 28 disposed in thegroove 26 and movable longitudinally with respect to the rails.

On the plate 21, motors 29 are carried, being electric motors, airdriven or of any other approved type whose driven shafts 30, carry emeryor other grinding wheels as at 3|.

Each plate 25 has a front or vertical wall 32 integral with it in whicha short shaft 33 is journaled and operable by a knob 34 thereon. Shaft33 carries a pinion 35 at the inner side thereof which is enmeshed withthe teeth of a rack 36' depending from the plate 22 relatively close tothe wall 32. Thus rotation of the knob 34 will rotate shaft 33 and causepinion 35 and rack 36' to slide the plate 25 transversely with respectto the rails, accordingly carrying with it the plate 21, motor 29 andthe grinding wheeL' A shaft 36 is journaled in the wall 32 and operableby a knob 31 thereon located above the knob 34. Shaft 36 is fastenedagainst sliding movement by a collar or the like as at 38. Such shaft 36as at 39 is provided with screw threads which are threaded to the plate21 in any suitable manner so that when knob 31 is turned, shaft 36 willbe rotated and the screw threads 29 and their engagement with the plate21, will slide suchplate and motor and grinding wheel thereon in adirection longitudinally with respect to the rails. The construction iswell adapted for grinding a pair of wheels at the same time, whichwheels are suggested as at 40 and carried by an axle 4|. Said wheels maybe on a locomotive or a car or any equivalent and the same are suitablyjacked up with respect to the rails in any suitable manner and attentionis called to the fact that it is unnecessary to remove the wheels ortheir axle from the locomotive or car in order to grind the peripheriesof the wheels. Wheels 40 may of course be driven in any suitable manner.When they are on Diesel locomotives, the electric power of thelocomotive is used to turn such wheels. When they are on steamlocomotives, the steam power is used to turn such wheels. Any suitablemeans may be used to drive the wheels 40 when they are car wheels but Iprefer to use the apparatus disclosed in my Patent No, 2,215,403 whichissued from co-pending application Serial No. 300,266, filed October 19,1939.

Attention is also called to the fact that the apparatus may be equippedwith but a single motor 29 and grinding wheel and plate 22 and plate 27in which event but one wheel 40 will have its periphery ground at atime, following which the parts mentioned will be transferred from onedovetail portion 23 to the other, and the second wheel 40 thereuponground at its periphery.

Various changes may be resorted to provided they fall within the spiritand scope of the invention.

I claim as my invention:

Apparatus of the class described comprising a beam adapted fordisposition transversely with respect to a pair of track rails, saidbeam having a horizontal wall to rest directly on the rails and avertical wall rising therefrom, depending bracket means carried by thehorizontal Wall to rigidly clamp said beam to the track rails, agrinding unit mounted on said beam for operation to grind the peripheryof a wheel of rolling stock, said unit comprising a vertical walldisposed against and welded to the first mentioned vertical wall, ahorizontal shelf integral with the last mentioned vertical wallextending forwardly therefrom at the top, webs connected to the shelfand last mentioned vertical wall, a bed plate disposed on said shelfhaving a depending front portion, a second plate slidably mounted on thebed plate, a third plate slidably mounted on the second plate formovement in a direction at a right angle thereto, said second platehaving an upper part rising at the front thereof and a lower part inline therewith depending at the front thereof, means mounted by thelower part geared to said portion, means mounted by said upper partoperable to slide the third plate, a motor mounted by the third plate,and grinding means rotatable by said motor on an axis parallel to thebeam.
